I am reading this paper this paper: Upgrade of a low-temperature scanning tunneling microscope for electron-spin resonance and found that for thermalization, they use 0 dB attenuators.  

Page 6: Having the finite cooling budget of our cryostat in mind, and noting that the heat transfer of the RF line is dominated by the micron thick Ag coating of the center conductor, we thermalized all SR cables using 0dB attenuators

I understand attenuators reduce signal intensity (power), but what does it mean to have a 0 dB attenuator?

What is the general purpose of 0 dB attenuators and in the paper is it just being used for thermal coupling?
